Under 1995 Joint Commission on the Accreditation of Healthcare Organizations (JCAHO) requirements, the repeat analysis was to be performed on the basis of each individual technologist, rather than being based on the entire facility as is the MQSA standard. JCAHO has since modified its standards to allow the analysis to be performed on a facility basis.
Whether the analysis is performed after the facility or the individual technologist has examined 250 mammogram patients is left up to the facility, but in all circumstances, the analysis must be performed at least quarterly in order to remain in compliance with MQSA. 21 C.F.R. 900.12(e)(3)(ii).
